Description

Technical Field

[0001] The invention relates to the field of dust removal bags, and in particular to a dust removal bag capable of reducing dust adhesion. Background Art

[0002] The dust bag is the heart of the bag dust collector. It is generally called a dust bag or a dust filter bag. The dust bag is a key part of the operation of the bag dust collector. Usually, the cylindrical filter bag is hung vertically in the dust collector.

[0003] In existing technology, bag filters are dry dust removal devices suitable for capturing fine, dry, non-fibrous dust. Filter bags are made of textile filter cloth or non-woven felt, utilizing the filtration properties of the fabric to filter dust-laden air. When dust-laden air enters the bag filter, large, high-density dust particles settle due to gravity and fall into the hopper. Finer dust particles are retained as they pass through the filter material, resulting in purification.

[0004] However, when a large amount of particulate matter adheres to the surface of the existing dust bags, the separation effect of the dust bags is affected. The dust bags need to be regularly removed and replaced from the bag collector, or their surfaces need to be cleaned. The above operations are labor-intensive and require the bag collector to be shut down before they can be operated, which affects the continuous operation of the bag collector.

A rubber ring is fixed on the inner ring surface of the connecting ring, and the rubber ring and the groove correspond one to one. After the tube body of the clamping ring is inserted into the connecting ring, the cloth bag cover is clamped between the rubber ring and the groove.

[0008] Preferably, a raised ring is fixedly mounted on the outer ring surface of the support ring, and the raised ring is a ring plate structure with an arc-shaped cross section. After the two ends of the bag cover are clamped by two sets of clamping rings, the bag cover is in a taut state, and the raised ring expands the bag cover outward.

[0009] Preferably, two hanging plates are symmetrically fixed on the surface of the connecting ring, and the hanging plates pass through a gap, and the gap is opened on the surface of the cloth bag cover.

In this process, the telescopic plate 15 strikes the striking circle 20, and the vibration shakes off the particles adsorbed on the surface of the bag cover 7.

[0029] Example 2

[0030] Refer to the attached Figure 3 and Figure 8On the basis of embodiment 1, in order to firmly fix the bag cover 7 on the connecting ring 1, the clamping ring 4 is an inverted "convex" shaped circular ring plate structure, and the top plate of the clamping ring 4 is against one side of the connecting ring 1. The outer ring surface of the tube body of the clamping ring 4 extending into the inner ring mouth of the connecting ring 1 is provided with a card groove 6. The card groove 6 is an annular groove, and there are multiple card grooves 6. The multiple card grooves 6 are arranged in an up and down manner. A rubber ring 5 is fixed on the inner ring surface of the connecting ring 1, and the rubber ring 5 and the card groove 6 correspond one to one. After the tube body of the clamping ring 4 is inserted into the connecting ring 1, the cloth bag cover 7 is clamped between the rubber ring 5 and the card groove 6; the outer ring surface of the support ring 3 is fixed with a raised ring 10, and the raised ring 10 is a ring plate structure with a circular arc cross-section. After the two ends of the cloth bag cover 7 are clamped by the two groups of clamping rings 4, the cloth bag cover 7 is in a taut state, and the raised ring 10 expands the cloth bag cover 7 outward; two hanging plates 9 are symmetrically fixed on the surface of the connecting ring 1, and the hanging plates 9 pass through the notch 8, and the notch 8 is opened on the surface of the cloth bag cover 7.

[0031] Turn the end of the cloth bag cover 7 inward and insert it into the inner ring opening of the connecting ring 1. Before inserting, make sure that the hanging plate 9 passes through the notch 8, and then push the clamping ring 4 into the inner ring opening of the connecting ring 1 until all the rubber rings 5 are inserted into the corresponding slots 6. At this time, the cloth bag cover 7 is squeezed into the corresponding slots 6 by multiple rubber rings 5, forming a clamping structure for the cloth bag cover 7. After both ends of the cloth bag cover 7 are clamped by the clamping ring 4, the middle part of the cloth bag cover 7 is close to the raised ring 10.

[0032] Example 3

[0033] Refer to the attached Figure 4 、 Figure 6 as well as Figure 7 On the basis of embodiment 2, in order to realize that after the connecting ring 1 is installed inside the bag dust collector, the particles adhered to the surface of the bag cover 7 can be shaken off without removing the connecting ring 1; a limit shaft 11 is fixed on the inner ring surface of the clamping ring 4, and the sleeve 12 is sleeved on the limit shaft 11, and a plurality of blades 13 are provided, and the plurality of blades 13 are arranged and distributed along the arc surface of the sleeve 12; a notch 14 is provided at the end of the blade 13 away from the sleeve 12, and the telescopic plate 15 is movably inserted into the notch 14; a reserved groove 16 is provided at the end of the telescopic plate 15 extending into the notch 14, and a rubber clamping block 17 is fixed inside the reserved groove 16, and one end of the rubber clamping block 17 is fixed to the surface of the notch 14; sliders 18 are fixed on both sides of the telescopic plate 15, and the slider 18 is slidably connected to the slide groove 19, which is provided on the surface of the blade 13, and the slide groove 19 is connected to the notch 14.

[0034] After the connecting ring 1 is installed inside the bag collector, as the airflow passes through the bag cover 7 from bottom to top, due to the large airflow, the airflow hits the blade 13, and the blade 13 is squeezed and pushed, driving the sleeve 12 to rotate around the limit shaft 11. In this process, the telescopic plate 15 knocks the impact circle 20, and the vibration shakes off the particles adhered to the surface of the bag cover 7, and as the airflow continues to hit the blade 13, the telescopic plate 15 is squeezed and pushed by the impact circle 20 and locked in the groove 14. At this time, the rubber clamp 17 is squeezed and deformed by the telescopic plate 15 until the telescopic plate 15 passes the impact circle 20, and the reserved groove 16 rebounds, and the rebounded reserved groove 16 pushes the telescopic plate 15 to reset.

[0035] In actual use, turn the end of the bag cover 7 inward and insert it into the inner ring opening of the connecting ring 1. Before inserting, make sure that the hanging plate 9 passes through the notch 8, and then push the clamping ring 4 into the inner ring opening of the connecting ring 1 until the rubber ring 5 is fully inserted into the corresponding card slot 6. At this time, the bag cover 7 is squeezed into the corresponding card slot 6 by multiple rubber rings 5, forming a clamping structure for the bag cover 7. After both ends of the bag cover 7 are clamped by the clamping ring 4, the middle part of the bag cover 7 is close to the raised ring 10; when the connecting ring 1 is installed inside the bag collector, it passes through the bag from bottom to top as the airflow Cover 7, due to the large air flow, after the air flow hits the blade 13, the blade 13 is squeezed and pushed, driving the sleeve 12 to rotate around the limit shaft 11. In this process, the telescopic plate 15 knocks the impact circle 20, and the vibration shakes off the particles adhered to the surface of the bag cover 7, and as the air flow continues to hit the blade 13, the telescopic plate 15 is squeezed and pushed by the impact circle 20 and locked in the groove 14. At this time, the rubber clamp 17 is squeezed and deformed by the telescopic plate 15. Until the telescopic plate 15 passes the impact circle 20, the reserved groove 16 rebounds, and the rebounded reserved groove 16 pushes the telescopic plate 15 to reset.
